Automated cooking apparatus having air flow regulation and reduced fire hazard

ABSTRACT

An automated cooking apparatus includes a computer system configured to store a recipe and a cooking apparatus that includes: a frying pan that can hold food ingredients, a heater that can heat the frying pan under the control of the computer system based on the recipe, an exterior body that can hold the frying pan and the heater, and a lid that can keep food ingredients in the frying pan while the food ingredients are stirred and mixed during cooking. A lid-movement mechanism can open and close the lid under the control of the computer system. A transport mechanism can move the frying pan and the cooking apparatus, under the control of the computer system, to mix, stir, or distribute the food ingredients in the frying pan to produce a cooked food.

BACKGROUND OF THE INVENTION

The present application relates to automated kitchen equipment, and specifically to automated cooking apparatus for cooking food ingredients.

In certain automated cooking apparatus, automated fry apparatus in particular, the mixing, stirring or distributing of food ingredients in the frying pan may be achieved by moving the frying pan. The food ingredients can have fast movement relative to the frying pan; and at times the food ingredients may jump. When food ingredients jump out of the frying pans, it not only creates waste but also presents a fire hazard. Some food ingredients, such as oil or fat, may be combustible. On the other hand, in traditional automated heated cooking, the outer surface of the frying pan may be over heated, and thus may start a fire. Such a fire can be dangerous in an automated cooking environment as very few humans, if any, are present. In addition, the heater not only may get in the way of the movement of the frying pan, but also may present a fire hazard.

Thus there is a need for an automated cooking apparatus that can provide proper stirring and mixing of food ingredients during cooking while minimizing food waste and preventing fire hazard. Moreover, there is a need to thermally insulate the heater and the exterior surface of the frying pan.

SUMMARY OF THE INVENTION

The present application discloses an automated cooking apparatus that overcome the drawbacks in conventional cooking systems. The disclosed automated cooking apparatus can provide proper stirring and mixing of food ingredients during cooking while minimizing food waste and preventing fire hazard.

DETAILED DESCRIPTION OF THE INVENTION

In some embodiments, referring to FIG. 1, a cooking apparatus 100 includes a frying pan 101 which may hold food or food ingredients, a thermal insulator 111, an electromagnet 121 and an exterior body (or frame) 131. The frying pan 101 is partially or entirely made of ferromagnetic material (such as iron or its alloys). The electromagnet 121 is configured to receive high frequency alternating current from an external source via the outlet 151, which can be controlled by a computer (not shown in FIG. 1). The alternating electromagnetic field generated by the electromagnet 121 can create conduction currents in the frying pan 101, which converts to thermal energy. The thermal insulator 111 keeps heat generated in the frying pan 101. The frying pan 101 is connected to the exterior body 131 by connectors 141, and the electromagnet 121 is connected to the exterior body 131 by connectors 142. The thermal insulator 111 is also connected to the exterior body 131. The thermal insulator 111 covers the exterior of the frying pan, and particularly it insulates the electromagnet 121 from the frying pan 101.

In some embodiments, referring to FIG. 2, a cooking apparatus 200 includes a frying pan 102 which may hold food or food ingredients, a thermal insulator 112, a heater 122, and an exterior body (or frame) 132 that holds the frying pan 102, the thermal insulator 112, and the heater 122. The frying pan 102 is connected to the exterior body 132 by connectors 143, and the heater 122 is connected to the exterior body 132 by connectors 144. The thermal insulator 112 is also connected to the exterior body 132. The thermal insular 112 insulates the heater 122 and the exterior of the frying pan 102 from the outside. The heater 122 includes a heating device which is a gas or oil burner with air and fuel injection and exhaust ventilation via the outlet 152. As part of the cooking operations, the heater 122 can be activated to heat the frying pan 102 based on a recipe under the control of the computer system (e.g. 310 in FIG. 3, 5, 6, 7 and 9, or 710 in FIG. 79).

The cooking apparatus 100, 200 in FIGS. 1 and 2 are suitable for cooking methods such as stirring frying, frying, stewing, pan fry, stir fry, deep fry, sautéing, hot sand frying . . . , etc. The term “frying pan” refers to a cooking container suitable for the previously described cooking methods. Frying pan may have a flat or curved bottom. Frying pan can also be referred to as a fry pan, a fry pot, a wok, a cooking pot, a pot, etc. One or more food ingredients can include oil, salt, sugar, vegetables, meat, water, pre-cooked food such as noodles and rice, etc. Different food ingredients may be added to the frying pan at different times and at different temperatures. The food ingredients can be stirred, mixed, and tumbled using mechanisms as described in detail below. It should also be noted that the heating device in the heater 122 may be implemented by an electric heater with resistance wires, in which case electric wires may be connected via the outlet 152.

In some embodiments, referring to FIG. 3, an automated cooking apparatus 300 includes a cooking apparatus 100, a frame 212 (or, a holder), and a turning pair consisting of a shaft 221 in a sleeve 222. The cooking apparatus 100 is rigidly connected to the shaft 221 through a connector 211, and the frame 212 is rigidly connected to the sleeve 222. The rotation of the shaft 221 around its sleeve 222 may be driven by a motor through a mechanical apparatus (e.g., as in FIGS. 6A-6B below), where the motor may be controlled by a computer system 310. Two shafts 231 and 233 are respectively connected to shafts 232 and 234 by the connectors 241 and 242 respectively. The frame 212 is rigidly connected to a sleeve of the shaft 231, so that the shaft 231 may rotate relative to the frame 212. A sliding pair consists of two mating parts 213 and 214, with the mating part 213 rigidly connected to the frame 212, and the mating part 214 rigidly connected a sleeve of the shaft 233. The sleeves of 232 and 234 are rigidly connected to a support frame 290. A gear 251 is mounted on the shaft 232 and has the same axis as the shaft 232. A second gear 252 is mounted on the shaft 234 and has the same axis as the shaft 234. The gears 251 and 252 are both engaged with a third gear 253 that is mounted on the shaft 235 of a motor 261. The gear 253 and the shaft 235 have the same axis. The motor 261 is mounted on the support frame 290. The axes of the shafts 231, 233, 232, 234 and 235 are all parallel to each other. The gears 251 and 252 have the same radius so that they may rotate synchronously. The distance between the axes of the shafts 231 and 232 is the same as the distance between the axes of the shafts 233 and 234; and the plane through the axes of the shafts 231 and 231 is parallel to the plane through the axes of the shafts 233 and 234. The motor 261 may be controlled by the computer system 310. As the motor 261 rotates, the shafts 232 and 234 may rotate synchronously, thus driving the shafts 231 and 233 into synchronous rotations, thus driving the frame 232, and hence the cooking apparatus 100 into a circular movement without self-rotation.

In the present disclosure, the computer system can include one or more processors, one or more controllers, memory that store recipe and control programs for cooking, communication devices for wired or wireless communications, a display device, and input and output device.

It should be noted that instead of being parallel to each other, the axes of the shafts 231, 233, 232, 234 and 235 may all pass through a same point.

It should also be noted that the sliding pair with mating parts 213 and 214 in the apparatus 300 may be modified as follows: the mating part 214 may be substituted by a cylinder (or a cylindrical shell) whose axis is the same as (or parallel to) the axis of the shaft 233, and the mating part 213 may be substituted by two walls that restrain the cylinder so the cylinder lies between the walls. The surface of the walls may be flat and both parallel to the plane through the axes of the shafts 233 and 231. The axis of the cylinder is parallel to the surfaces of the two walls. The distance between the surfaces of the two parallel walls may be equal to the diameter of the cylinder, so the cylinder may fit well in between the walls.

It should be further noted that the transport mechanisms in the automated cooking apparatus 300 may be replaced by other transport mechanism that can move the frame 212. The movements may include but are not limited to circular, linear, planar, spherical, cyclic, vibratory, oscillatory movements or combinations thereof, and the magnitude of the movements may further be adjusted. Providing the capability of a plurality of complex cyclic, vibratory or oscillatory movements allows more effective stirring, tumbling, aeration, and mixing of food ingredients, which enable a wider range of cooking recipe and cooking styles. It should also be noted that the cooking apparatus 100 may be replaced by other types of frying pans, with or without a built-in heating.

In some embodiments, referring to FIGS. 4A-4B, an unloading apparatus 400 includes a cooking apparatus 100, a frame (or holder) 212, and a turning pair with shaft 221 and sleeve 222 as mating parts. A connector 211 connects the cooking apparatus 100 with the shaft 221. The shaft of a free wheel 323 is mounted on an extension of the connector 211 (FIG. 4A). A bearing is inserted between the free wheel 323 and its shaft so that the free wheel 323 may rotate freely around its shaft. The sleeve 222 is rigidly connected to a frame 212. A second turning pair has a shaft 331 and sleeve 332 as mating parts, with the sleeve 332 rigidly connected to the frame 212. A wheel 334 is mounted on the shaft 331 (FIG. 4B). The wheel 334 has a carved track 335 so the free wheel 323 may fit in and slide in the carved track. The rotation of the wheel 334 around the axis of the shaft 331 is driven by a motor (not shown in Figure) which is controlled by a computer system (e.g. 310 in FIG. 3, not shown in FIGS. 4A and 4B). As the wheel 334 rotates, the free wheel 323 is moved, thus rotating the connector 211 around the axis of the shaft 221. The cooking apparatus 100 may thus be rotated around the axis of the shaft 221. This can be used to unload the cooked or semi-cooked food from the frying pan.

It should be noted that the cooking apparatus 100 in the apparatus 400 may be substituted by other frying pans, with or without built-in heating. It should also be noted that the unloading apparatus 400 may be substituted by a rotation mechanism that rotate the transport mechanism that moves the frying pan.

In some embodiments, referring to FIG. 5, an automated cooking apparatus 500 includes the automated cooking apparatus 300, a lid 405, and a lid-movement mechanism as follows. A shaft 271 is connected to the lid 405 through a connector 273. The sleeve of the shaft 271 is connected with the frame 212, so the shaft 271 may rotate relative to the frame 212. A motor (not shown in Figure) can drive the rotation of the shaft 271 relative to the frame 212 under the control of a computer system 310. As the motor rotates the shaft 271, the lid 405 may be moved between a position to cover the frying pan of the cooking apparatus 100 and a position away from the frying pan.

In some embodiments, referring to FIG. 6, an automated cooking apparatus 600 includes the automated cooking apparatus 300, a lid 406, and a lid-movement mechanism as follows. An end of a rod 281 is connected to the lid 406. The rod 281 and a mating part 282 form a sliding pair. The mating part 282 is mounted on the frame 212, so that the rod 281 may slide linearly relative to the frame 212. A powered mechanism (not shown in Figure) can drive the sliding of the rod 281 relative to the frame 212 under the control of a computer system 310. As the powered mechanism slides the rod 281, the lid 406 may be moved between a position to cover the frying pan of the cooking apparatus 100 and a position away from the frying pan. It should be noted that there are many different implementations for the powered mechanism, e.g., a lead screw mechanism or ball screw mechanism powered by a motor, or a pneumatic, hydraulic or electromagnetic cylinder.

In some embodiments, referring to FIG. 7, an automated cooking apparatus 700 includes a cooking apparatus 100 (with detailed structures shown in FIG. 1), a lid 406 that can cover the frying pan, and a frame (or holder) 491. A shaft 411 is connected to the exterior body 131 of the cooking apparatus 100 through a connector 412. A sleeve of the shaft 411 is connected with the frame 491, so the shaft 411 may rotate relative to the frame 491. A motor (not shown in Figure) drives the rotation of the shaft 411 relative to the frame 491 (e.g., through a mechanical apparatus as in FIGS. 4A-4B), and a computer system 710 may control the motor. The shaft 411 and its sleeve, the connector 412 and the motor driving the rotation of the shaft 411 form an unloading mechanism. The sleeves of two shafts 421 and 422 are connected with the lid 406. The shafts 421 and 422 are respectively connected to shafts 425 and 426 through connectors 423 and 424 respectively. The sleeves of the shafts 425 and 426 are both connected to the frame 491. The axes of the shafts 421, 422, 423 and 424 are parallel to each other. A motor (not shown in Figure) may drive the rotation of the shaft 425 relative to the frame 491 (e.g., through a mechanical apparatus as in FIGS. 6A-6C), under the control of the computer system 710. The shafts 421, 422, 425, 426, their sleeves, and the connectors 423 and 424 form part of a lid-movement mechanism that opens and closes the lid 406. It should be noted that, the shaft 421 and its sleeve form a primary turning pair of the lid-movement mechanism, where the sleeve is connected to the lid 406, and the shaft 421 may be actively rotated by a motor under the control of the computer system 710; while the shaft 422 and its sleeve form a secondary turning pair of the lid-movement mechanism, where the sleeve is connected with the lid and the shaft 422 is passively constrained to rotate around the axis of the shaft 426. The motor driven rotation of the shaft 421 and the constraint on the movement of the shaft 422 together move the lid 406 to or away from the frying pan.

A stabilization mechanism consists of a shaft 418 whose sleeve is connected with another shaft 419. The shaft 419 has sleeves that are connected with a support frame 493, so that the shaft 419 may freely rotate relative to the support frame 493. The axes of the shafts 418 and 419 are not parallel to each other.

A transport mechanism includes a shaft 431 whose sleeve is connected with the frame 491. The shaft 431 is connected with another shaft 433, where the axes of the shafts 431 and 433 may not be parallel. The axes of the shafts 431 and 433 may intersect at 90 degrees of angle, although this is not a requirement. A connector 432 connects the sleeve of the shaft 433 and a shaft 435, where the axes of the shafts 433 and 435 may not be parallel. The sleeve of the shaft 435 is connected to a shaft 436, where the axes of the shafts 435 and 436 may not be parallel. The axis of the shaft 436 may be horizontal although this is not a requirement. The shaft 436 has some sleeves that are connected with a shaft 441, wherein the axes of the shafts 436 and 441 may not be parallel. The axis of the shaft 441 may be vertical and intersect with the axis of the shaft 436 at 90 degrees of angle, but this is not a requirement. The shaft 441 has a sleeve that is connected with a frame 494 so that the shaft may rotate around its own axis relative to the frame 494. A chain wheel 445 is mounted on and is concentric with the shaft 441. A second chain wheel 447 is mounted on and is concentric with the shaft 443 of a motor 442 under the control of the computer system 710. A chain 446 wraps around the chain wheels 445 and 447. The axes of the shafts 431, 441, 418 and 419 may intersect at a point, but this is not a requirement. Through the chain 446, the motor 442 may drive the shaft 441 in a continuous rotation around its own axis, and thus drive the shafts 436, 435, 432, 433 and 431 into a rotation around the axis of the shaft 441. Together with the stabilization mechanism, such a motion may cyclically move the frame 491 and hence the cooking apparatus 100. In case the axes of the shafts 418 and 419 intersect at a point, the cooking apparatus 100 are restricted to spherical motions around the point of intersection. If the axes of the shafts 441, 431, 418, 419 all intersect at a point, then in the movements produced by the transport mechanism and constrained by the stabilization mechanism, the trajectory of a “center” point (e.g., a point on the intersection of the frying pan and the axis of the shaft 431) on the cooking apparatus 100 is a circle.

It should be noted that the lid-movement mechanism responsible for opening and closing the lid 406 is mounted on the frame 491. Thus the lid-movement mechanism moves together with cooking apparatus 100 (including the frying pan) in the movements produced by the transport mechanism and restrained by the stabilization mechanism.

An adjustment mechanism includes shafts 450 and 451 which are connected with the frame 494, and their respective sleeves. A partial gear 460 is connected with the sleeve of the shaft 450; and a second partial gear 461 is connected with the sleeve of the shaft 451. The partial gears 460 and 461 are engaged, and have the same radius. The sleeves of the shafts 450 and 451 are respectively connected with the sleeves of two shafts 454 and 455 by connectors 452 and 453 respectively. The shafts 454 and 455 are respectively connected with the sleeves of the shafts 458 and 459 by the connectors 456 and 457 respectively. The shafts 458 and 459 are both connected with the support frame 493. A partial gear 468 is connected with the sleeve of the shaft 458; and a second partial gear 469 is connected with the sleeve of the shaft 459. The partial gears 468 and 469 are engaged, and have the same radius. Another partial gear 471 is connected with the sleeve of the shaft 459. The shaft 473 of a gear 472 has a sleeve which is connected with the support frame 493. The gears 471 and 472 are engaged, and a motor (not shown in Figure) drives the rotation of the gear 472 around its axis under the control of the computer system 710. As the gear 472 is rotated, the partial gear 471, and thus the sleeve of the shaft 459 and the partial gear 469 are rotated around the shaft 459. Then, the partial gear 468, the sleeve of the shaft 458, and the sleeves of the shafts 450 and 451 are all rotated, thus moving the frame 494 and hence the shaft 436 (up or down as visible in Figure). As a result, the angle of inclination of the connector 432 may be changed, and thus the angle between the axes of the shafts 441 and 431 may be adjusted. The angle between the axes of the shafts 441 and 431 affects the magnitude of the cyclic movement produced by the transport mechanism.

It should be noted that the adjustment mechanism in the automated cooking apparatus 500 may be replaced by a jack, or by apparatus that can move the frame 494 relative to the support frame 493. It should be further noted that the transport mechanism in the apparatus 500 may be replaced by other transport mechanisms that can move the frame 491. The cooking apparatus 100 may be substituted by a frying pan of other type, with or without built-in heating.

In some embodiments, referring to FIGS. 8A-8C, an automated lid system 800 includes a lid 406 for a frying pan, and two shafts 421 and 422 whose sleeves are connected with the lid 406. Two shafts 421 and 422 are respectively connected to shafts 425 and 426 through connectors 423 and 424 respectively. The sleeve 427 of the shaft 425 and the sleeve 428 of the shaft 426 are both connected to a frame 491 (FIG. 8A). (The frame 491 may be moved by a transport mechanism as in the apparatus 700 in FIG. 7.) A free wheel 429 has a shaft connected with an extension of the connector 423, and a bearing may be installed between the free wheel 429 and its shaft so that the free wheel 429 may rotate freely relative to the connector 423. A shaft 481 has a sleeve 482 which is connected with the frame 491. A wheel 483 is mounted on the shaft 481 (FIG. 8B). The wheel 483 has a carved track 484 so the free wheel 429 may fit in and slide in the carved track. The rotation of the wheel 483 around the axis of the shaft 481 is driven by a motor (not shown in Figure) which may be controlled by a computer system (e.g. 310 in FIG. 3, 5, 6, 7, 9, or 710 in in FIG. 7, not shown in FIGS. 4A-4B, 8A-8C). As the wheel 483 rotates, the free wheel 429 is moved, and the connector 423 is rotated around the axis of the shaft 425. The lid 406 may thus be moved to different positions as shown in FIGS. 8B and 8C. In the position of FIG. 8B, the lid 406 may lid or seal a frying pan, while in FIG. 8C, the lid may be moved away from a frying pan.

The lid 405 and the lid-movement mechanism in the automated cooking apparatus 500, or the lid 406 and the lid-movement mechanism in the automated cooking apparatus 600 or 700 or the apparatus 800 are mounted on a frame (212 in FIG. 5 and 6 or 491 in FIGS. 7-8C) that may be moved by a transport mechanism, so that the lid 405 or 406 may be moved together with the frying pan by the transport mechanism. The lid may be able to cover the frying pan while the transport mechanism moves the frame and the frying pan to stir, mix, and distribute the food ingredients in the frying pan. In particular, the lid, in the position to cover the frying pan, may be used to help prevent the food ingredients from jumping out of the frying pan during the stirring, mixing and distributing process. This is different from the traditional automated lid that is mounted on a base frame, in which case the lid needs to stay away from the frying pan when the frying pan is moved by a transport mechanism.

It should be noted that the lid 405 or 406 can have a different shape and be made by different materials. It can be partially made by a net, or can have an opening, so that the heated air or vapors may escape from the interior of the frying pan, while the lid covers the frying pan to prevent the food ingredients from jumping out.

In some embodiments, referring to FIG. 9, an automated cooking apparatus 900 includes the automated cooking apparatus 300, a lid 506 and a cover 507, and their respective movement mechanisms as follows.
